A regenerative refrigerating apparatus which can increase the speed of cooling and heating a subject to be cooled. The specific constitution of the regenerating type refrigerating apparatus includes a pressure control means 4 having a compressor 4a, a high pressure selector valve 4b, and a low pressure selector valve 4c, an expanding/compressing unit 1 having a room temperature end 1a and a low temperature end 1b, and a regenerating unit 2 having a room temperature end 2a and a low temperature end 2b, carries out heat transfer to a subject to be cooled, and is comprised of a flow path for working gas connecting the low temperature end 1b of the expanding/compressing unit and the low temperature end 2b of the regenerating unit with each other, and simultaneously extending to the subject to be cooled 7. Consequently, it is possible to significantly increase the utilization ratio of the refrigerating apparatus, and to widely apply the refrigerating apparatus to sensors and semiconductor manufacturing apparatuses.
A regenerative refrigerating apparatus including a pressure control means having a compressor, a high pressure selector valve and a low pressure selector valve, an expanding/compressing unit having a room temperature end and a low temperature end on both ends, and a regenerating unit having a room temperature end and a low temperature end on both ends, thereby carrying out heat transfer to a subject to be cooled, the apparatus characterized by comprising a flow path for working gas connecting said low temperature end of said expanding/compressing unit and said low temperature end of said regenerating unit with each other, and simultaneously extending to said subject to be cooled.
A pulse tube refrigerating apparatus including a pulse tube having a room temperature end and a low temperature end on both ends, a regenerator having a room temperature end and a low temperature end on both ends, a phase control means for communicating with said room temperature end of said pulse tube so as to control pressure fluctuation and phase difference of working gas, and a pressure control means communicating with said room temperature end of said regenerator, and having a compressor, a high pressure selector valve and a low pressure selector valve, thereby carrying out heat transfer to a subject to be cooled, the apparatus characterized by comprising a flow path for working gas connecting said low temperature end of said pulse tube and said low temperature end of said regenerator with each other, and simultaneously extending to said subject to be cooled.
